+# INSTRUCTIONS:
+# 1. Open your existing agent/Cargo.toml
+# 2. Add these dependencies to the [dependencies] section
+# 3. Run `cargo build` to fetch and compile dependencies

+# VERSION COMPATIBILITY NOTES
+# ============================================================================
+#
+# tokio 1.35 - Latest stable async runtime
+# serde 1.0 - Standard serialization framework
+# serde_json 1.0 - JSON support for serde
+# once_cell 1.19 - Thread-safe lazy initialization
+# log 0.4 - Logging facade
+# env_logger 0.11 - Simple logger implementation
+#
+# All versions are compatible with Rust 1.70+ (latest stable)
+#
+# ============================================================================
+# FEATURE FLAGS EXPLANATION
+# ============================================================================
+#
+# tokio "full" feature includes:
+# - tokio::process (for spawning Claude Code process)
+# - tokio::time (for timeout handling)
+# - tokio::io (for async I/O operations)
+# - tokio::sync (for Mutex and other sync primitives)
+# - tokio::rt (async runtime)
+#
+# If you want to minimize binary size, you can use specific features:
+# tokio = { version = "1.35", features = ["process", "time", "io-util", "sync", "rt-multi-thread", "macros"] }
+#
